The FCD-E1E is a multiplexer and rate and interface converter for extension of serial data, Ethernet and E1 services or fractional E1 over SDH/SONET networks.

Offering a wide range of serial interfaces (V.35, V.36, V. 24, RS-530, X.21) with selectable sync data rates of n X 64 kpbs, data port rates are selectable for any multiple of 64 kbps up to 1,984 kbps. Unframed E1 can be supported up to 2.048 Mbps.

The integral LTU ensures a range of up to 2 km (1.2 miles) and is software selectable.

The unit can be programmed to assign data automatically from the data port into consecutive timeslots or the user can assign timeslots manually.

Multiple clock source selection

Multiple clock source selection ensures maximum flexibility. Timing for the E1 main link and sublink may come from the recovered receive clock, an internal oscillator, or the data port

The unit interconnects with RAD modular DXC products and E1 equipment from other vendors to support multilink star applications such as access to SDH networks, FCD, and Megaplex units.

Ethernet extension

The FCD-E1E’s Ethernet interface allows LAN-to-LAN connectivity over TDM. The product’s 10/100BaseT interface supports VLAN frames, auto-negotiation, and automatic learning and aging. It transparently connects FCD-E1Es to remote LANs over E1 links. It filters Ethernet frames and forwards only frames that are destined for the WAN.

FCD-E1E supports VLAN tagging and priority labeling according to 802.1p&q. Enhanced QoS, supporting strict/weighted fair queue mechanism, with 802.1p/DSCP/IP Precedence priority.

Standards compliant

The E1 interface is compatible with carrier-provided E1 services. The product complies with ITU recommendations G.703, G.704, G.706, G.732, G.823, and G.826.

Management

For easy management, the FCE-E1E features an LCD front panel for menu-driven management using three pushbuttons.

Front panel LEDs indicate power, alarms, and diagnostic loopback operation. Rear panel LEDs on the E1 interfaces indicate local and remote sync loss.

Status and diagnostic information is defined, configured, and monitored using any of the following methods:

• Menu-driven management using the front panel LCD with three pushbuttons
• ASCII terminal connected to the async control port
• Telnet
• RADView element manager

FCD-E1E is a compact standalone unit. A rack mount adapter kit enables installation of one or two (side-by-side) units in a 19-inch rack.
